Abstract: 

A formal group is a power series that behaves like a group law and exhibits deep connections to number theoretic results from reciprocity laws to elliptic curves, and from local class field theory to dynamical systems. In this talk, I will introduce formal groups, describe their more salient features, and trace some of their unexpected cameos since (and sometimes before) their invention/discovery more than 70 years ago, ending with an answer to a recent question from the internet (and Jonathan Lubin).
